Hi People
I would like to understand what is the best strategy to implement a new BI enviroment.
We just have to acquire the BI plataform and we have doubts if you have to develop the reports using universe or BW queries.
We don't have HANA yet, only the ERP with relational database, we have configured two connections to ECC in BI platform: OLAP and Relational connection.
1) What is the advantages and disadvantages of each type of connection (OLAP and Relational)?
2) Is the universe the best approach? Do we have to stop creating BW queries and start to work only with universes?
3) I also have doubts how to apply a security police in OLAP connection since the user name and password is configured in the connection. Does the BI platform check the BW authorization from the user that is accessing the report? We have a cost center report to develop, but the users can only access the information for the cost center he is authorized to. Is it possible to restrict this access in a OLAP connection?
4) Why some BI tools can only access OLAP connections and do not access universe, for example, analysis for office and analysis for OLAP?
Thank you,
Emerson
